While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. We'll use ROE to examine Wuxi DK Electronic Materials Co.,Ltd. (SZSE:300842), by way of a worked example.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Is ROE Calculated?

ROE can be calculated by using the formula:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Wuxi DK Electronic MaterialsLtd is:

28% = CN¥378m ÷ CN¥1.3b (Based on the trailing twelve months to December 2023).

The 'return' is the profit over the last twelve months. That means that for every CN¥1 worth of shareholders' equity, the company generated CN¥0.28 in profit.

Does Wuxi DK Electronic MaterialsLtd Have A Good ROE?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, Wuxi DK Electronic MaterialsLtd has a better ROE than the average (5.9%) in the Semiconductor industry.

That is a good sign. Bear in mind, a high ROE doesn't always mean superior financial performance. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk .

How Does Debt Impact Return On Equity?

Most companies need money -- from somewhere -- to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining Wuxi DK Electronic MaterialsLtd's Debt And Its 28% Return On Equity

Wuxi DK Electronic MaterialsLtd does use a high amount of debt to increase returns. It has a debt to equity ratio of 2.59. There's no doubt the ROE is impressive, but it's worth keeping in mind that the metric could have been lower if the company were to reduce its debt. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
